SPEIFICATION' forming part of Letters Patent Flo. 411,414, dated September 24, 1889.

' Application filed June 28,1889. Serial No. 315,906. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM A. ANrHoNY, of Manchester, Connecticut, have invented a new and useful Electro-Magnetic Separator, of which the following description and claims constitute the specification, and which is illustrated by the accompanying sheet of drawings.

Figure 1 of the drawings is a side elevation of the apparatus. Fig. 2 is a plan view thereof. Fig. 3 is a cent-ral vertical Section on the line a b of Fig. 1. Fig. 4 is aside elevation of a modified form of the apparatus shown in the other figures.

The nurneral 1 indicates a mass of iron in the formof a spool and with thick heavy heads.

That spool is wound full withra coil of insulated wire 2,the ends of which are connected with the collector-rings 3 and 4,' respectively,

and those collector-rings are provided with the brushes and 6, respectively, and those brushes are connected with the electrical conductors 7 and 8, respectively.

The spool 1 is provided with journals which revolve in bearings in the frame of the apparatus, and is caused to 'evolve by the pulley 9, Which receives motion throughthe belt 10 from the pulley 11.

The spool 1 carries upon its periphery the endless non -magnetic apron 12, and -that apron is also carried upon the periphery of.

the roller 13. The roller 14 revolves in bearings in the frame of the apparatus parallel with the spool 1 in substantially the position shown in Fig. 1, and is caused thus to revolve by the apron 12, the lower reach of which passes with tension over the roller 14 inmediately in the rear of the spool 1. The

receptacle 15 .is placed below the forward part of the periphery of the spool 1, and the receptacle 16 is placed below the rearward part of the periphery of the roller 14.

The numeral 17 indicates the mixed magnetic and non-magnetic substances which are to be separated, and the nunerals 18 and 1'9 indicate those magnetic and non-magnetic substances, respectively, after they are separated by the apparatus.

The modified form of Fig. 4 consists of the spool 1, which is denticalin all respects and connections with the spool 1 in the other figures, and consists also of the spout 20, which conducts mixed magneticand nonnagnetic substances and discharges them upon the periphery of the spool, and consists, finally, of the brush or scraper 21,Which 'removes the magnet-ic bodies in those substances from the periphery of the spool.

The mode of. operation of the apparatus of Figs. 1, 2, and 3 is as follows: The pulley 11 runs the-belt 10 in the direction indicated by the arrow adjacent to thatbelt, and revolu- `tion is lthereby imparted to the pulley 9 and the spool 1, and motion is thus imparted `by that spool to theapron 12 in the direction indicated by. the arrow adjacent to that apron, and revolution is also imparted to the roller 14 in the direction opposite to that of the revolution of the spool 1. An electric current is oontemporaneously 7o caused to pass throughthe coil 2 from any suitable generator of electricity by means of the electrical connections 3, 4, 5, 6, v7, and 8. The mixed magnetic and non-magnetic substances are deposited and spread upon the upper side of the upper reach of theapron 12. As that part of that apron which carries those substauces is carried forward around the periphery of the spool 1, the magnetic 'bodies therein are attracted andl held to the outer surface of the apron against the attraction of gravitation, while the non magnetic substances 19 fall into the receptacle 15. The magnetic bodies are held to the outer surface of the apron as long as the inner surfacethereof is in contact with the spool 1 and where that contact ceases the magnetic attraction of the spool therefor operates, unless positively prevented, to draw the magnetic bodies which are clinging to the outer and under surface of the apron backward along that surface; but the roller 14 positivelyholds those bodies in placeagainst that under surface until they are carried to the upper side of the periphery of that roller, Whence they are carried by that periphei'y to the rearward side thereof and there allowed to fall into the receptacle 16.

The l,mode of operation of the apparatus of Fig. 4! is as follows: Motion is imparted to the spool 1 in the direction of the arrow adjacent to that spool by the same means as in the IOO -and non-magnetic substances are condueted. 'by the spout. from any suitable 'eceptacle thereof, and are deposited and spread upon the forward part of the -upper side of the periphery of the spool. -As that section of that perher goes forward with the .revolution of the spool the nagnetic 'bodies in those* substances are attracted and held thereto against. the attraction of' gravitation, while I 'Is V ceptacle 22.- The magnetie bodies 'are held V to the v-peripheryof the spooluntil vthey are' the non-magnetic substances fall into the reycarried thereby into contact with the brnsh or scraper 21, by which they are dislodged and removed far 'enough from the periphery of the spool to allow the attraction of gravitation to overbalance the thus-diminished magnetism,

these, because it Will develop and thus to carry those bodies into the receptacle 23.

The roller 14 maybe onitted from the apparatue' of Figs. 1, 2, and 3 and the lower reach of the apron 12be pcrmitted topass directly from the'lowerside of the periphery of the spool 1 to the lower side of the roller 13; but in that case a scraper or brush, or other analogous device, will be required to remove the nagnetic bodies from the surface of the apron. So, also, the electro-magnetic part ofV the apparatus, instead of being a mass of iron n the form of. a spoo1,.woundrwith an insulated col, may sometimes be 'al Siemens drumarmature constructed and eleetricallyfconnected as in a ldynamogwor it may be a Siemens shuttle-arnature, orit may be an Varma-l lture of the Gramnetype; .but the e'oiledspool shown in the drawings is better tha' .eith`er of a much-stronger magnetic field than either of them.,

I claim as myinvention-efl from between the roller'and the'apron, all,

substantiallyv as deseribed. v

2. The combination of the spool 1, wound with the coil 2 and electrically connected, substantially as described, with the endless nonmagnetic apron 12, passin'g around and in` contact With a part-of the periphery of thespool 1 and adaptejd to carry mixed magnetic and non-magnetic substances `upon its outer surface and' to, drop .the non-magnetic bodies in those substances at one'place, with a roller revolving parallel ,toj the spool 1 and lunder the apron 12, and adapted to hold the'magnetic bodies in-those substances betweenit and that apron, and thus to carry them far enough out of the magneticv fieldv to enable them to drop at another place when released from between the roller' and the 'apron,-all 1 substantially as deseribed.

3. In an electro-magnetic separator, the combination vof the. spool 1,' wound with .the coil 2 and electrically connected, substantially as described, and means, substantially as' set forth, for removing magnetic substances from the magneticfieldjof-'thatspool and coil, all

substantial'ly as d'esc'ribed;
